The 10 Best Ab Exercises to Strengthen Your Core

The Pilates curl is also referred to as the C-shape curl; this movement targets the deepest part of your core, the transversus abdominis. "It's a simple exercise but when done properly it has a profound effect on the strength of your core," Brandenburg says. "It also helps alleviate back pain."

1. Start by lying on your back.
2. Bend your knees and place your feet on the ground.
3. Place your hands behind your head with your elbows wide or keep the straight (like shown above).
4. Inhale to prepare, then exhale, and curl forward to lift your head, neck, and shoulders.
5. Chin should move forward, creating a c-shape in the spine.
6. Repeat for 2 sets of 10 focusing on the breath cues.
